Self-Fulfilling Risk Panics : An Expected Utility Framework

Even if an asset has no fundamental uncertainty with a constant dividend process, a stochastic sentiment-driven equilibrium for the asset price exists besides the well-known fundamental equilibrium. Our paper constructs such sentiment-driven equilibria under general utility functions within an OLG structure. Our paper further shows that the existence of sentiment-driven equilibria is robust in a standard infinite-period model as long as the pricing kernel is affected by the asset price
